Numerical evidence for a mass gap in three-dimensional SU(2)

Summary, in English

Numerical evidence for a nonvanishing 0⁺⁺ glueball mass in three-dimensional SU(2) is presented. By using a long-distance correlation Monte Carlo method we obtain m₀⁺⁺ = (4.7±1.2)√σ in the β-range 4.0-6.5. The measurements are consistent with 1/β-scaling. The relevance of this result for SU(2) in four dimensions at finite temperature is briefly discussed.
